Surface Water Conversion

Design and construction information about our surface water supply.

Surface Water Supply

To provide surface water to our Groundwater Reduction Plan "GRP" Participants, we first have to construct the infrastructure necessary to treat and convey 88 million gallons of water per day (MGD) from the east side of the Houston Region to northern Fort Bend County. Getting surface water to the North Fort Bend Water Authority "NFBWA" is estimated to cost a total of $1.3 billion. Our projects include:

Who is getting surface water and when will it happen?

An additional 68.5 MGD of surface water is projected to be available to NFBWA in 2025. Once we have the additional surface water, our new surface water connections will begin getting surface water from the NFBWA. Visit our online interactive map to see the current and planned future surface water connections.

The NFBWA is striving to convert as many of our GRP Participants as possible to surface water. Just because a surface water connection is not currently planned, does not mean that the Retail Utility will not be connected in the future.

Reach out to us if you have any questions about if or when your retail water provider will receiving surface water.

Water Plant Design

The NFBWA constructs the distribution line and meter station to our GRP Participant connections. Our GRP Participants design and construct facility improvements required to receive surface water, including conversion to chloramine disinfection.

New water plant facilities located within our boundaries should be designed to accommodate surface water and chloramine disinfection infrastructure. Our Design Manual includes design criteria that must be followed for surface water conversions.

Contact us to us to determine if your facility is eligible for reimbursement of facility improvements related to surface water conversion.
